Greetings,

Last night I started working on a 51J-4, actually its a Beckman labled 
unit.
There are three broken ferrite tuning cores. One in the KC deck and 
two in the
MC deck. Are these all physically the same or is each core designed
differently? Anyone have some available for sale or trade? I think I 
will need
more than three as I have another 51J-4 with a couple of broken cores
thats stashed away as well.
